Examination with an Otoscope

Dear Friends,
As per discussion regarding the use of an Otoscope for a satisfactory ear examination,herewith uploading a VDO of the proper use of an Otoscope.
Attention may also be paid to the subtle points...like i) How to hold the instrument in the hand.
                                                                               ii) How to retract the pinna.
Regards,
Amol.
